Abstract

The utility model relates to a medical apparatus technical field is an infusion condition monitoring device particularly, including laser emitter, grating inductor, casing and fixed bolster, infusion condition monitoring device set up on the infusion burette of dropping liquid chamber lower part, a recess has been seted up to its characterized in that casing upper surface, grooved underside has seted up L shape hollow out construction, forms the opening on one side L shape hollow out construction extends to the casing edge, L shape hollow out construction another side top is equipped with laser emitter and grating inductor, laser emitter and grating inductor are installed respectively on groove inner side wall, L appears and still is equipped with calliper in the hollow out construction, is equipped with the fixed bolster outside the casing. Compared with the prior art, the utility model, its advantage lies in: can not rock the liquid level that leads to infusing because of the infusion bottle and undulant and cause the measuring deviation, can rock or the liquid level undulant and produce the wrong report because the transfer line, can not drag the transfer line because of the patient leads to the force variation to thereby lead to measured deviation.

Description

A kind of transfusion state supervising device

[technical field]

The utility model is related to medical equipment technical field, specifically a kind of transfusion state supervising device.

[background technology]

Often occur due to human negligence in infusion process, just terminate transfusion when causing transfusion to be nearly completed hastily and extract The situation of needle tubing, more serious situation is that transfusion completes to settle and do not extract syringe needle and cause air intravasation to cause medical thing Therefore.

Original infusion process supervising device, there is following several.1) infusion monitoring bottle weight, when weight saving is to a fixed number Value sends warning.2) infusion monitoring bottle liquid level, by light line reflection, infusion monitoring pipe drip chamber liquid level, when woven hose liquid When dropping down onto below drip chamber, light areflexia, supervising device is reported to the police, but this supervising device can be torn due to woven hose, liquid Rock and affect the reflective condition for monitoring light so as to cause false alarm in face.

China's patent CN201520782594.6 discloses a kind of transfusion monitoring device, and the infusion device can be according to biography of weighing The data of sensor are reported to the police, and warning nurse stopping infusion works or dressing, but such supervising device can pull transfusion due to patient Bottle causes infusion bottle weight readings to produce error, so as to affect measurement accuracy.

[utility model content]

The purpose of this utility model is to solve the deficiencies in the prior art, there is provided a kind of safe and reliable, easy to use and energy The infusion process supervising device of reply complex jamming.

To achieve these goals, design a kind of transfusion state supervising device, including generating laser, grating inductor, Housing and fixed support, described transfusion state supervising device is arranged on the transfusion drip tube of drip chamber bottom, it is characterised in that Housing upper surface offers a groove, and groove floor offers a L-shaped engraved structure, and L-shaped engraved structure is while extend to housing Edge forms opening, and L-shaped engraved structure another side top is provided with generating laser and grating inductor, generating laser and grating Inductor is separately mounted on groove madial wall, and clamp are additionally provided with L-shaped engraved structure, and hull outside is provided with fixed support.

Switch and buzzer are set on described housing.

Described groove is used to place drip chamber, and the laser that generating laser sends passes through drip chamber, drip chamber bottom Transfusion drip tube is arranged in L-shaped engraved structure.

Described fixed support one end is fixed on housing bottom, and the other end is connected with housing sidewall, consolidating at housing bottom Fixed rack bending takes the shape of the letter U, and the fixed support of housing sidewall is also bent into U-shaped, and fixed support forms integral structure.

Light from a kind of transparent medium be slanted through another kind of transparent medium when, the direction of propagation can typically change (refraction), And angle changing (refraction angle) this principle relevant with the density of transparent medium, judge drop by monitoring the refraction path of light Whether there is liquid in sap cavity, when no liquid in drip chamber, be issued by alarm signal, clamping body locking woven hose terminates Transfusion, so as to avoid malpractice.

The utility model compared with the existing technology, has an advantage in that：

1. the utility model will not be rocked because of infusion bottle causes to infuse liquid fluctuating and cause the deviation for measuring, because only The propagation path for wanting light is air-transfusion liquid-air, and incidence angle is fixed, then the propagation path of light is exactly to fix, Will not rock because of woven hose or liquid fluctuating and produce wrong report.

2. the utility model will not pull woven hose because of patient causes the change of power.

[specific embodiment]

Below in conjunction with the accompanying drawings the utility model is described in further detail, the structure and principle of this transfusion state supervising device It is very clearly for the people professional to this.It should be appreciated that specific embodiment described herein is only to explain this reality With new, it is not used to limit the utility model.

Referring to Fig. 8, this transfusion state supervising device blocks woven hose drip chamber.

Referring to Fig. 1,2,3,4,5, transfusion state supervising device, including device body, the generating laser (2) on body, Grating inductor (3), clamp (7) and buzzer (6).

Referring to Fig. 6, beam of laser is projected by laser head, through drip chamber, through liquid refracting, be mapped to the grating on opposite Plate, the A points of original screen panel are activated.

Referring to Fig. 7, at the end of transfusion is close to, no liquid in drip chamber, the path of laser changes, and is mapped to the light on opposite During grid, the activation point of grating turns to B by A changes.

Because the point that grating is activated changes, the process chip of this device receives what grating activation point changed Signal, Jing after information processing, sends signal triggering buzzer, carries out audible alarm, and touches caliper unit, vises woven hose, Slow down infusion process, wait medical personnel to stop transfusion.
